Abstract

A tiled display device includes a first panel. The first panel includes a first lower substrate and a first upper substrate disposed opposite to the first lower substrate. The first upper substrate includes a first upper surface, a first lower surface and a first side surface located between the first upper surface and the first lower surface. The tiled display device further includes a second panel disposed adjacent to the first panel. The second panel includes a second lower substrate and a second upper substrate disposed opposite to the second lower substrate. The second upper substrate includes a second upper surface, a second lower surface and a second side surface located between the second upper surface and the second lower surface. The second side surface is disposed adjacent to the first side surface. A portion of the first side surface is not perpendicular to the first upper surface or the first lower surface, and a portion of the second side surface is not perpendicular to the second upper surface or the second lower surface.

Claims

exact text as granted — not AI-modified

What is claimed is:

1. A tiled display device comprising:
a first panel including a first lower substrate and a first upper substrate disposed opposite to the first lower substrate, wherein the first upper substrate includes a first upper surface, a first lower surface and a first side surface, and the first side surface is located between the first upper surface and the first lower surface; and
a second panel disposed adjacent to the first panel, wherein the second panel includes a second lower substrate and a second upper substrate disposed opposite to the second lower substrate, the second upper substrate includes a second upper surface, a second lower surface and a second side surface, the second side surface is located between the second upper surface and the second lower surface, and the second side surface is disposed adjacent to the first side surface;
wherein a portion of the first side surface is not perpendicular to the first upper surface or the first lower surface, and a portion of the second side surface is not perpendicular to the second upper surface or the second lower surface; wherein the portion of the first side surface includes an inclined portion connected to the first upper surface.

2. The tiled display device of claim 1 , wherein the first side surface further includes a side portion perpendicular to the first upper surface, and a roughness of the side portion is different from a roughness of the inclined portion.

3. The tiled display device of claim 1 , wherein the inclined portion includes a first sub inclined surface and a second sub inclined surface, the second sub inclined surface is connected to the first sub inclined surface, the first sub inclined surface and an extension line of the first upper surface have an included angle, the second sub inclined surface and the extension line of the first upper surface have an another included angle, and the included angle is different from the another included angle.

4. The tiled display device of claim 3 , wherein the included angle ranges from 20 degrees to 45 degrees.

5. The tiled display device of claim 3 , wherein the another included angle ranges from 45 degrees to 70 degrees.

6. The tiled display device of claim 1 , wherein the first side surface includes two inclined portions, and the two inclined portions are respectively connected to the first upper surface and the first lower surface.

7. The tiled display device of claim 1 , wherein the portion of the second side surface includes an inclined portion connected to the second upper surface.

8. The tiled display device of claim 1 , wherein the portion of the second side surface includes two inclined portions, and the two inclined portions are respectively connected to the second upper surface and the second lower surface.

9. The tiled display device of claim 1 , wherein the first side surface includes a curved portion connected to the first upper surface.

10. The tiled display device of claim 1 , wherein the first side surface includes two curved portions connected to the first upper surface and the first lower surface respectively.

11. The tiled display device of claim 1 , wherein the portion of the second side surface includes a curved portion connected to the second upper surface.

12. The tiled display device of claim 1 , wherein the portion of the second side surface includes two curved portions connected to the second upper surface and the second lower surface respectively.

13. The tiled display device of claim 1 , wherein the first side surface includes a curved portion connected to the first upper surface and the first lower surface.

14. The tiled display device of claim 1 , wherein the portion of the second side surface includes a curved portion connected to the second upper surface and the second lower surface.

15. The tiled display device of claim 1 , wherein the first lower substrate includes a third upper surface, a third lower surface and a third side surface, the third side surface is located between the third upper surface and the third lower surface, and a portion of the third side surface is not perpendicular to the third upper surface or the third lower surface.

16. The tiled display device of claim 15 , wherein the portion of the third side surface includes an inclined portion or a curved portion.

17. The tiled display device of claim 1 , wherein the second lower substrate includes a fourth upper surface, a fourth lower surface and a fourth side surface, the fourth side surface is located between the fourth upper surface and the fourth lower surface, and a portion of the fourth side surface is not perpendicular to the fourth upper surface or the fourth lower surface.

18. The tiled display device of claim 17 , wherein the portion of the fourth side surface includes an inclined portion or a curved portion.

19. The tiled display device of claim 1 , further comprising a cover substrate disposed on the first panel.
